The correct answer is the second choice - peer review process in scientific research exists in order to verify that the conclusions that are made are supported by the data. You cannot make a valid conclusion if you do not have enough evidence or data to prove it - this is why your peers have to go through your research to make sure everything is done according to the rules of scientific research.
Hope this helps.
You need to know the areas region and its landform I guess not sure though
During bread making, metabolism of simple sugars by yeast produces carbon dioxide which makes the bread rise.
The essential ingredients of bread dough are flour, water and yeast. As soon as these ingredients are stirred together, enzymes in the yeast and the flour cause large starch molecules to break down into simple sugars.
The yeast metabolizes these simple sugars and exudes a liquid that releases carbon dioxide and ethyl alcohol into existing air bubbles in the dough. If the dough has a strong and elastic gluten network, the carbon dioxide is held within the bubble and begins to inflate it, just like someone blowing up bubble gum.
As more and more tiny air cells fill with carbon dioxide, the dough rises, and so we see bread rising.
Ribosomes. Ribosomes which synthesize proteins are found in the rough endoplasmic reticulum.
